This report provides information to professional industrial, scientific, and technical photographers as well as research personnel on filtration with glass and infrared-absorbing and -reflecting filters. Glass and infrared filtration is a simple and effective method to reduce the radiation heat transfer associated with continuous high-intensity tungsten lamps. The results of a filtration experiment conducted at the NASA Lewis Research Center in Cleveland, Ohio, are explained. The figures provide starting points for quantifying the effectiveness of various filters and associated light intensities. The combination of a spectrally selective reflector (hot or cold mirror) based on multilayer thin-film prin-ciples and heat-absorbing or infrared opaque glass results in the maximum reduction in temperature rise with a minimum of incident light loss. The report recommends use of a voltage regulator to further control temperature rise and incident light values.
